A MAGNETIC BALANCE FOR MEASURING MAGNETIC SUSCEPTIBILITIES.
Abstract
The final design and construction of a Weiss-Foex magnetic balance were completed and the balance was adapted to make measurements at low temperatures. The balance was used to measure the paramagnetic susceptibility of a rare earth-transition metal compound and to determine the temperature dependence of the susceptibility. The initial measurements and calibration led to an over-all accuracy of =6.08% in the range of susceptibilities of from 2 to 100 X 0.000001 emu/gram. Ferrous ammonium sulfate and nickel chloride were used as standards for calibration. The compound YCo2 was investigated and proved to have a paramagnetic moment which followed the Curie-Weiss Law. The 'Curie constant' was found to be .19 X 0.000001 emu-K/ gram and the 'Weiss constant' was found to be 53 K. (Author)
